Claims (1)

Tragbare Werkzeugmaschine, insbesondere Tischkreissäge,
mit einem Gehäuse (1), einem darin angeordneten elektrischen Antriebsmotor (2) mit
einer Anschlußeinrichtung (3) zum Anschluß an ein Netz mit niedriger Netzfrequenz, insbesondere 50 Hz und mit einem vom Antriebsmotor (2) angetriebenen Werkzeug (4), insbesondere dem Sägeblatt der Tischkreissäge, dadurch gekennzeichnet,
daß der elektrische Antriebsmotor (2) als Asynchronmotor, ggf. auch als Synchron­ motor, ausgeführt ist,
daß die Anschlußeinrichtung (3) einen Frequenzumrichter (5) aufweist, durch den die niedrige Netzfrequenz auf eine hohe Betriebsfrequenz des elektrischen Antriebsmo­ tors (2), insbesondere eine Betriebsfrequenz von 300 bis 400 Hz, umgesetzt wird,
daß der elektrische Antriebsmotor (2) mit einer der höheren Betriebsfrequenz ent­ sprechenden höheren Drehzahl, insbesondere einer Drehzahl von 18.000 bis 24.000 min-1 betrieben wird und
daß der elektrische Antriebsmotor (2) über ein Untersetzungsgetriebe (6) mit dem Werkzeug (4), insbesondere dem Sägeblatt, gekuppelt ist, das dementsprechend mit niedrigerer Drehzahl, insbesondere einer Drehzahl von 3.600 bis 4800 min-1, betrie­ ben wird.Portable machine tool, in particular table saw,
with a housing ( 1 ) and an electric drive motor ( 2 ) arranged therein
a connection device ( 3 ) for connection to a network with a low network frequency, in particular 50 Hz, and with a tool ( 4 ) driven by the drive motor ( 2 ), in particular the saw blade of the table saw, characterized in that
that the electric drive motor ( 2 ) is designed as an asynchronous motor, possibly also as a synchronous motor,
that the connection device ( 3 ) has a frequency converter ( 5 ), by means of which the low mains frequency is converted to a high operating frequency of the electric drive motor ( 2 ), in particular an operating frequency of 300 to 400 Hz,
that the electric drive motor ( 2 ) is operated with a higher operating frequency, correspondingly higher speed, in particular a speed of 18,000 to 24,000 min -1 and
that the electric drive motor ( 2 ) via a reduction gear ( 6 ) with the tool ( 4 ), in particular the saw blade, is coupled, which is accordingly operated at a lower speed, in particular a speed of 3,600 to 4800 min -1 .
